Description

The intelligent flow device

The utility model belongs to the flow detection utensil and makes the field.

Background technology of the present utility model: existing flow detector, as water meter and refuelling station's Fuel-filling metering device, the former low precision, the latter is that stationary structure, body are big, complex structural designs, manufacturing cost height, (car) carries with oneself, next Fuel-filling metering accuracy, the consumer can't verify that particularly taxi driver's repercussion is more strong.

Purpose of design of the present utility model: designing a kind of one is to have automatic error correction function, accurate measurement, make things convenient for the consumer to detect at any time; The 2nd, volume is little, light self-weight, easy to carry, cheap.

Design proposal of the present utility model: utilize the power of liquid stream to drive the ball-type turbine, the pulse that utilizes magnet steel on the turbine and electronic sensor to produce mutually again with certain magnetic field intensity, utilize pulse signal input computer to carry out the exact figure conversion again, in order accurately to align " O " position, reach the requirement of country's metering extra fine grade, this computer assembly adopts the automatic error correcting technique in the VCD machine, thereby reaches the purpose of accurate measurement.Its organization plan: intelligent flow device, it comprises detection components and computer display module, jack in the computer display module (12) and plug (1) are pegged graft, housing (9) is an one-piece construction, the lower part of frame cavity is a sensing chamber, impeller assembly (5) is positioned at sensing chamber, and the impeller end in the impeller assembly (5) studs with magnet steel (4) or Hall switch, and sensor (13) is an inductive switch.Rectifier (7) top is analysed and observe and is trapezoidal, bottom and has several rectification holes.Rectifier (7) is positioned on the convex edge of housing, cavity in its below housing is the pressure chamber, have diversion tunnel on the wall between pressure chamber and sensing chamber, the import of diversion tunnel is communicated with, exports straight to the blade in the impeller assembly in the sensing chamber with the center of bottom, pressure chamber, the top of rectifier is provided with the oil-resistant seal ring (8 that internal diameter does not wait, 10), sensor (13) is embedded on the inwall of sensing chamber, its signal output part is by signal wire plug (1), damping block (2) is positioned at the oil-out of housing, and damping block (2) is to have several pod apertures.Vertically have the signal wire resettlement groove on the wall of housing (9).The centre of plug (1) head is signal output part (0), and both sides are (-) utmost point and (+) utmost point.

The utility model is compared with background technology, and the one, the integrally-built design of housing has guaranteed that the liquid of surveying does not run leakage; The 2nd, have the rectifier of V font groove and diversion tunnel, guaranteed the reliable rectification of institute's fluid measured; The 3rd, the setting of pressure chamber and sensing chamber, the accuracy of the assurance fluid flow of examining; The 4th, impeller assembly, sensor and damping block structure Design have guaranteed the reliable transmission of the signal of examining; The 5th, have automatic error correction function, accurate measurement-through Provincial Technical Supervision Bureau detect metering reach extra fine grade (conformity certification number: No. the 3100th, Zhejiang amount machine word), volume is little, make things convenient for the consumer with oneself (car) carry and low cost of manufacture.
